Functional closure of the orbicularis oris muscle and esthetic reconstruction of nasolabial components are impossible in patients with severely deformed premaxilla. Here, we review a surgical strategy for patients with unremedied premaxilla retrospectively.
Vomerine ostectomy and premaxillary setback with nasolabial repair were performed in 12 patients with bilateral cleft lip and palate. The mean age of patients was 21.7 months. The extent of ostectomy varied between 3 and 11 mm. There were no serious complications from defective perfusion to the premaxilla or the philtral flap. The follow-up period ranged from 2 to 25 months. Proper positioning of the premaxilla and satisfactory nasolabial esthetics were achieved in all patients.
We performed nasolabial repair after premaxillary setback without jeopardizing the premaxillary segment or the philtral flap. Our surgical strategy could be recommended in poor socio-economic circumstances due to the cost effectiveness of limiting the number of surgeries.
对于严重畸形的前颌骨患者，口轮匝肌的功能性闭合以及鼻唇结构的美学重建是不可能实现的。在此，我们回顾性地研究一种针对未矫正前颌骨患者的手术策略。
对12例双侧唇腭裂患者实施了犁骨切除术及前颌骨后缩并鼻唇修复术。患者的平均年龄为21.7个月。切除范围在3至11毫米之间。未出现因前颌骨或人中瓣灌注不良导致的严重并发症。随访期为2至25个月。所有患者均实现了前颌骨的正确定位以及满意的鼻唇美学效果。
我们在不危及前颌骨段或人中瓣的情况下，于前颌骨后缩后进行了鼻唇修复。由于限制手术次数具有成本效益，我们的手术策略在社会经济条件较差的情况下值得推荐。
